Mick Mulvaney, 100% loyal and fully committed to his position as acting POS. Ooops...I meant "COS."

Since taking on the jobs duties in late December, Mulvaney has tapped roughly half a dozen former aides to accompany him to the White House, with several more potentially on the way. And while its not surprising for any new chief of staff to install people he knows and trusts in top jobs, administration officials say, Mulvaneys latest moves illustrate the extent to which he is settling into his new job despite its temporary-seeming title.
By keeping the acting title, he gives himself an out in case things go south, said a Republican close to the White House. He can say he was only the acting chief, if his relationship with the president sours in six months. Then, he wont be fired.
Essentially, Mulvaney has become an acting chief of staff in name only.
Mulvaney recently hired Rob Blair, an associate director of national security programs at the Office of Management and Budget, as the White Houses new senior adviser to the chief, according to one administration official and the Republican close to the White House. Blair will join four other budget agency veterans who moved into the West Wing in late December, including the new principal deputy-chief-of-staff Emma Doyle.
